√ Integrated with calibrator, load box, regulator, easy to connection.
√ Secondary current to be switched by rotary.
√ External regulator and current injection could be connected to increase or adjust capacity easily.
√ Protective circuit, reliable and safe.
√ Under CT/PT measuring, the impedance of secondary circuit or the active component and idle component of admittance could be measured at any time.
√ Polarity could be indicated automatically, and auto break differential current/voltage circuit to insure the safety and alarming by sound light.
√ To be used as rectangular coordinate system AC potentiometer, to measure the AC low current or low voltage.
√ To be used with isolating PT and control unit to measure the secondary drop voltage of PT.
√ The reference CT/PT or two stage CT/PT or Inductive Divider all could be used as standard reference during measuring.
√ LCD screen, English interface.
√ 40 groups CT storage, the 1% error results also can be stored.
√ PC and corresponding software could be connected to operate.
√ Build-in printer.
